Selliguea (8) - including Christiopteris, in contrast to Smith et al (2006) and
Crypsinus and Phymatopteris.
Thylacopteris (1)
Tricholepidium (3) - may require further study in relation to the type-species of
Leptochilus.
Grammitidaceae Grammitidaceae - it is not accepted here to include this family within Polypodiaceae.
Calymmodon (1)
Chrysogrammitis (1)
Ctenopterella (3)
Dasygrammitis (1)
Micropolypodium (1)
Oreogrammitis (8)
Prosaptia (5)
Radiogrammitis (1)
Scleroglossum (2)

Hymenophyllaceae
Hymenophyllaceae
Hymenophyllum (12 - 13)
Trichomanes (31-36) - treated here as one genus consistent with the treatment of
Hymenophyllum and in contrast to Smith et al. (2006).
Dicksoniaceae Dicksoniaceae - including Cibotiaceae.
Cibotium (1)
Cyatheaceae
Cyatheaceae
Cyathea (14 - 16) - some authors have separated Alsophila, Gymnosphaera and
Sphaeropteris from Cyathea, but Holttum’s arguments versus Tryon in favour of their
status as subgenera are preferred here and Smith et al. (2006) are not followed in
separating them.
Dennstaedtiaceae
Dennstaedtiaceae
Dennstaedtia (3) - including Emodiopteris.
Histiopteris (1)
Hypolepis (2)
Microlepia (14)
Monachosorum (1) - included here, as by Fraser-Jenkins (2008), on the basis of its
obviously similar morphology, and apparently also supported by Smith et al. (2006).
Pteridium (2)
Lindsaeaceae Lindsaeaceae - included by Kramer & Green within Dennstaedtiaceae, but separated here
as being morphologically distinct, which is apparently supported by Smith et al.
(2006).
Lindsaea (23 - 28) - several species reported from the Andaman and Nicobar Islands
